What changed?
Why?
In case of mutable state inconsistency, either due to our bug or DB returning stale data, new (and invalid) history node with higher transaction ID will shadow the valid history node. Although update of mutable state is protected by CAS, the new (and invalid) history is still present in DB. TrimHistoryBranch API is introduced for to trim this kind of invalid history nodes.
